Title: Method of manufacturing nonvolatile semiconductor memory device
Inventor: UEDA MICHIHITO
IPC: H01L21/8247
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the problem that, in the conventional MFMIS formation method, a MFM section is formed after the formation of a MIS section in order to make a capacitor area in an MFM section smaller than that in a MIS section, which increases the number of processes and requires a margin for alignment of masks for the MFM section and MIS section, resulting in the increase in size of the device. SOLUTION: By reducing the size of a mask for etching, the area of a capacitor of the MFM section which consists of a first electrode, ferroelectric thin film, and second electrode can be made smaller than the area of a capacitor of the MIS section which consists of a substrate, gate insulation film, and the first electrode, by one and the same mask. As a result, a margin for only one time is required for alignment of masks in an exposure and development process, which reduces the size of a nonvolatile semiconductor memory device itself.
